DRAFT-EVEN ER.

SPECIFICATION forming part of Letters Patent No. 711,799, dated October 21, 1902. Application filed August 4, 1902. Serial No. 118,397. (No model.)

To all whom, it may concern.-

Be it known that LHENRY A. TE PoEL,a citizen of the United States, residing at Prague,

in the county of Saunders and State of Ne The present invention relates toimprove:

ments in eveners, and more particularly to the four-horse type.

The object in View is the provision of a structure which shall prevent strains and which shall be adapted to be adjusted to various positions.

With this and other objects in view the invention consists of certain novel constructions, combinations, and arrangements of parts, as will be hereinafter fully described and claimed.

In the accompanying Qdrawings, Figure 1 represents a top plan view of an evener embodying the features of the present invention. Fig. 2 represents an enlarged transverse vertical section taken on the plane of line 2 2 of Fig. 1.

Referring to the drawings by numerals,1 indicates any suitable plow-beam, preferably constructed of two plates secured-together; but it may be formed of a single plate bifurcated at its ends. Between the plates of beam 1 is positioned a vertically-adj ustable block 2, which is formed with apertures for receiving securing-bolts 3 3, passed transversely therethrough and through the plates forming the beam 1. Each of the plates forming the beam 1 is provided with a series of apertures 4: 4, which receive the bolts 3 3, whereby the said block 2 may be adjusted vertically rela-v tive to said beam 1. Suitable bolts 5 5 penetrate block 2 and are firmly secured thereto and have their outer ends connected by a suitable strip 6, firmly binding a transverse draftbar 7 to the block 2, said bar having a slightlybeveled rear edge 7, whereby the bar will be held longitudinally in a horizontal plane, but transverselyin a diagonal plane. Near the ends of bar 7 are secured forwardly-extending links 8 8, carrying antifriction-rollers 9 9, about which are passed chains 10 10, connected by an adjusting-rod 11, said bar being formed at its ends with hooks 12 12, engaging any one of the links of said chain, it being apparent that more or less of either chain may thus be employed, as may be desired. The outer free ends of chain 10 carry any suitable draft device, as doubletrees 13 13, having attached suitable whiffletrees l 14.

In operation the block 2 may be adjusted to any desired height for effecting the depth of furrow ofaplow carried by beam 1, and the upward pitch or. diagonal plane of bar 7 will produce an evenness of movement, owing to the upward tendency of all draft devices for plows, which is due to the fact that the plowbeam is itself attached well beneath the horizontal plane of the point of draft. It will be observed that the bar 7 extends approximately twice the distance on one side of the block 2 that it does upon the other and that no auxiliary brace-rods are necessary owing to the particular form of attachment just described. The position of the bar 7 to one side of the center relative to the beam 1 makes it possible for three of the draft-horses to Walk upon the land side and only necessitates one walking in the furrow, and the chain and rod connections will produce an evenness of draft regardless of the fact that more than one-half of the source of power is to one side of the center.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a device of the class described, the combination with a suitable beam having an aperture formed in one end of the same, a block seated in said aperture, means for permitting the vertical adjustment of said block, a bar rigidly secured to the beam, chains carried near the ends of such bar, and a draft apparatus carried by said chains, and means for longitudinally adjusting the chains, substantially as set forth.

2. In a device of the class described, the combination of a suitable beam having an aperture in one end, a block mounted in said aperture and capable of vertical adjustment, a bar rigidly secured to said block, antifriction means carried by the end of said bar, chains passing through said antifriction means, means for adjusting said chains, and

draft apparatus carried by said chains, substantially as set forth.

3.- In a device of the class described, the combination of a suitable beam having an aperture in one end, a block vertically adjustable therein, a bar rigidly secured to said block, chains carried near the ends of said bar, a rod connecting said chains and formed with hooks forpermitting the longitudinal adjustment of the chains, and draft apparatus carried by the free ends of said chains, substantially as set forth.

4:. In a mechanism of the class described, the combination with a suitable beam having an aperture at one end, of a bar arranged transversely of said beam, means for permit- HENRY A. TE POEL.
